Keyless Entry/Start Stop not functioning

Hi there,
2011 Continental FS Speed
I have an issue with the Keyless entry start/stop system.
When I try to unlock the car, I should press the unlock button on the key to enter, cannot enter by grabbing the door handle, when trying to start the car, I only can start it by inserting the key in the slot, I cant start it by the Start/Stop button.
I have the code:
ACCESS/START AUTHORIZATION
DTC 01049:009 VEHICLE VOLTAGE TERMINAL 50 - OPEN CIRCUIT/SHORT CIRCUIT TO GROUND
And as well:
BATTERY CHARGER
01049:008 VEHICLE VOLTAGE TERMINAL 50-IMPLAUSIBLE SIGNAL

I have no issues using the car like this but I keep replacing the key because it wears out quickly.
Thank you.
